Trees that let their leaves fall off before winter are called deciduous trees.

Here are some examples of deciduous trees:

* Oak

* Maple

* Birch

* Willow

* Poplar

* Elm

* Ash

* Beech

* Cherry

* Apple

Deciduous trees lose their leaves in the fall to conserve water and energy during the cold, dry winter months. They then regrow new leaves in the spring.
